Nagios Support Forum

Hey everyone,

So i recently set up a memory usage check, thanks to the nagios support forum team, and now for some reason on one of my servers im getting a weird error message on the website. Im getting this on the website:

AWK=/bin/awk

then when i try to run the check_mem.sh on the nagios machine with :

/usr/lib/nagios/plugins/check_nrpe -H 10.100.50.43 -c check_mem

i get this as output:

What happens when you run it locally? On the remote system run:

get pretty much the same script, with the addition of this:

(standard_in) 2: syntax error
(standard_in) 1: syntax error

Run the following command and show the output:

i fixed it, it was a problem on the server itself, thanks for the help though

No problem, have a good week.
